Whether it be a second story addition, a garage conversion, sunroom, home theatre, that dream primary suite or an in-law apartment... you deserve a home that works for you. Commitment and dedication as a reliable builder is at the heart of every construction project we complete as we work hard to exceed expectations in terms of workmanship and final finished project. Everything is done right, from the foundation up - with no shortcuts, no surprises, and craftsmanship you can trust.

Timeless Living Spaces that Grow with You

We craft more than renovations - we create enduring value through timeless design and elevated execution that add value to your property. A thoughtful, well-built addition can increase your home's value by 20-30%. Even better, it gives your home more curb appeal and buyer interest if you ever decide to sell. Square footage is one of the top ways to raise home value!

Key reasons to consider a home addition:

✓ Expanding Your Living Space

✓ Increasing Property Value

✓ Accommodating a Growing Family

✓ Creating a personalized space

✓ Enhancing your home’s aesthetics

✓ Improving overall functionality

More space, more functionality, more value… a well-designed home addition will transform the way you live.

What Our Clients Say

“Mike Stephens & Gems Custom Homes provide the best quality and work for all your home building/renovation needs. We are currently finishing our third project with Mike, and we could not be more pleased with the results. His quality of work is exceptional, and his attention to detail is unparalleled. He is great with communication and stays true to his word at all points throughout the construction process. We used him to build our primary residence (twice), and he is currently completing an add-on garage apartment. It flawlessly blends with the original home, and we are really pleased with it. He is the best in town, no doubt about it. We're lucky to have him as our builder and could not recommend him highly enough.”
